Distress call emitting device
First Claim
1. A distress call emitting device adapted to be installed outside a room or a house occupied by a person who may require a rescue effort comprising:
- an alarm unit for emitting a distress message by sound and/or light;
alarm triggering means including a radio receiver for receiving a radio signal from a remote transmitter, said alarm triggering means capable of generating a command signal in response to the received radio signal;
a controller for activating said alarm unit upon receiving the command signal from said alarm triggering means; and
a battery power source for powering said alarm unit, said alarm triggering means, and said controller,said remote transmitter being of a wristwatch type configured to be worn on a wrist of a user.

Abstract
The distress call emitting device comprises an earthquake sensor for detecting an earthquake of a prescribed intensity or greater and/or a receiver for receiving a radio signal from a remote transmitter. Therefore, even when the user is unable to call for a help, the distress call emitting device of the present invention produces a distress call in his behalf by sound and/or light. The distress call can be initiated either by detecting the intensity of the earthquake or by operating a remote transmitter which may be carried by the user. If the device is linked to a telephone line, the distress call can be made also through a telephone line. Thus, even when the user is too weak to call for a help by his own effort, the device is either automatically activated by an earthquake or remotely activated by pressing a switch on a portable transmitter.
